KNOXVILLE, Tenn. (WVLT) -- Buying organic peaches, apples, and other produce at the grocery store can rack up your bill.
"For most of us, we don't have the money to buy everything organically," said Dr. Pete Slack, America's Leading Stress Expert. "I have four boys. It's expensive to go to the grocery store."
According to Dr. Pete, organic foods are free of pesticides and sometimes those pesticides can be toxic.
"They have a link to cancer, ADHD, even infertility," said Dr. Pete.
Dr. Pete had good news. He said you don't have to buy everything organic.
Scientists and researchers with the Environmental Working Group put out a study this year that showed a list of what you should buy organic and other foods where the price is not worth it.
The first set is called the Clean 15. These are fruits and vegetables that use the least amount of pesticides.
The next set is called the Dirty Dozen. Dr. Pete said this list of produce has so many chemicals that you should try to always buy them organically.
"Even if you wash them very well, they have pesticides in the nature of that fruit," said Dr. Pete.
He added most organic produce will cost you about a dollar extra.
"You're going to actually save so much money later on in life because you're going to be so much healthier for it," said Dr. Pete.
If your budget only allowed you to buy one organic food, Dr. Pete suggested that you make it strawberries this year.
